Today we'll be learning about adding and subtracting sig figs!
Rule 1: Add or subtract like you normally would.
I DONT GET IT !
Rule 2: Round the sum or difference to the least amount of significant figures after the decimal
I help you! Its simple addition and rounding! Just find the least amount of figures after the decimal !
2.21-1.2= 3.33 = 3.3 but since there is 1 sig fig after the decimal, the final answer has 1 decimal.
